Cody Adams, thanks for sharing your experience. I do not normally deal with super boomers like yours. I have dealt with the RUM's, the Win Mags, and the Weatherby magnums. I try to tell the people not to use the Leupold standard, Redfield Junior, or other dovetail front/double screw rear setup. but there are always people that insist on having them put on harder kicking magnums. I remember one vividly. a guy came in with a full Leupold setup and scope and asked me to mount the scope. The rifle was a featherweight 300 Win Mag. I asked him if he really wanted this scope and this mounting setup combination. He said, "yes". I did not even say another word but, "I will have it done in 3 days." I still have that whole setup in my shop to show what one round of 180 grain of factory 300 Win Mag will do to these setups. BTW, the scope had to be sent to Oregon/Leupold for a new scope tube. the double screw assembly and the mating surfaces were blown out, the scope tube was bent, and the front ring was slightly loosened. the good news was all 3 of the 6-48 screws held. I have yet to find anything good about the Leupold standard bases and rings. but that is just me.
